Steps to Take in Case Material Is Exposure to the spilled material may be irritating or harmful. Follow personal protective Released or Spilled: equipment recommendations found in Section 8 of this SDS. Additional precautions may be necessary based on special circumstances created by the spill including; the material spilled, the quantity of the spill, the area in which the spill occurred. Also consider the expertise of employees in the area responding to the spill. Ventilate the contaminated area. Isolate area. Keep unnecessary personnel away. Remove soiled clothing and launder before reuse. Surfaces may become slippery after spillage. Avoid contact with clothing. Avoid contact with material. Avoid creating and inhaling spray or mist. Avoid contact with skin and eyes. Prevent the spread of any spill to minimize harm to human health and the environment if safe to do so. Wear complete and proper personal protective equipment following the recommendation of Section 8 at a minimum. Dike with suitable absorbent material like granulated clay. Gather and store in a sealed container pending a waste disposal evaluation. Neutralize spill with a weak acid such as vinegar or acetic acid Absorb spill with inert material (e.g., dry sand or earth), then place in a chemical waste container Section 7 Handling and Storage

Handling: Wash thoroughly after handling. Do no eat, drink or smoke when using this product. Avoid creating and inhaling dust. Avoid contact with skin. Storage: Store in a secure area suitable for corrosives. Storage Code: Green - general chemical storage Section 8 Protection Information
